Q:What’s the production standard of aluminum coil?
GB/T3880-2006 mechanical standard GB/T3190-1996 chemical standard
Q:The specification of thermal insulating aluminum coil
4-0 In general, the chemical engineering products for thermal insulation is 0. According to the International standard, the thickness tolerance is +-5%.02MM. according to industrial standard, it is +-0. The production crafts are embossed and plain sheet.
Q:What is the common color of aluminum coil membrane?
The blue transparent membrane is the most common.
Q:Is the aluminum coil with damaged side still useful?
The side of tire, also called side wall, is the thinnest and most fragile. Side wall damages can be divided into swell and scratch. The swell is often caused by external force (The car is trapped in pit or on curb when you are driving fast). It can cause the cord thread break so that the rubber of the tire side wall cannot be fixed and tightened. The size of the swell is often as big as that of an one-yuan coin and will become bigger as the traveling distance increases. Under such circumstance, it is recommended to replace the tire. Scratch is usually caused by bad roads or debris on the road. It is recommended to replace the tire if the scratch in the side wall is obvious and the cord thread break. If the front wheels have such damages, the tire should be replaced as soon as possible (Because the steering, braking and driving is mainly based on the front wheels.). If there is no spare tire on site, change the front damaged tire with the rear tire and drive to an appropriate place.
Q:How to use aluminum sheet to roll a 12m-long aluminum coil with a diameter of 184cm?
According to project experience, first you should check the specification of the aluminum sheet and then design crafts such as connection method, installation and transportation according to equipment.
Q:How to identify the quality of color coated aluminum coil and sheet?
Color coated aluminum coil is a kind of aluminum coil. As for qualified color coated aluminum coil, the surface has no impression, holiday and damage through the coating, and also no ripple, scratch and swell. All these are easy to see. However, the most important is the color difference of the color coated aluminum coil which is not obvious but will influence the decoration effect. Now the surface of curtain wall aluminum sheet will also be treated with electrostatic spraying. The power coating materials can have dozens of colors and realize good decorative effect, with polyurethane, polyethylene expansion resin and epoxy resin as raw materials, high color retention pigment as auxiliaries.
Q:How heavy and long is the aluminum rolling on average?
The aluminum density is 2.7, and the average weight of molded aluminum coil is within 3.5 tons. But that depends on the molded width and thickness. The wider and thicker it is , the shorter it is.
Q:Why the aluminum sheet crack after?
Maybe the crack existed during welding but you didn’t notice. And then it expands and becomes obvious when acted on by external force in circling process. The reason may be the welding craft. Besides, I suggest more comprehensive tests after welding, such as penetrant test.
Q:What are the best rust-proof coils? Please tell me the model and manufacturer in Shangdong. Thank you.
3003 aluminum coil, AL-Mn series alloy, is the most widely used rust-proof aluminum with the density being 2.73. It is applicable to insulation projects such as pipe insulation, packaging, machine parts, refrigerator, air conditioning and ventilation pipes and other wet environment.
Q:Why does the end face of aluminum coil have grease spots?
Process one without coolant to see whether there are spots. There is a layer of alumina membrane on the blank face of aluminum coil, which will react with basic coolant when heating through processing.
